WIED: A Web Modelling Language for Modelling Architectural-Level Information Flows
AbstractThe ability to reliably and consistently develop systems that utilise Internet and Web technologies has become increasingly important. These systems are typically both functionally complex and information-rich, and have a number of unique characteristics that should imply specific changes to the development processes, methods and models that are adopted. One aspect that has received increasing attention is information modelling for these applications, particularly with respect to aspects such as navigation models and their relationships to the underlying content. These models have typically focussed on modelling at a relatively low-level, however, and have failed to address higher-level aspects, such as architectural and even business process modelling. The paper introduces a formal information modelling set which can be considered as a companion to to an existing modelling language - WebML - that facilitates information modelling at this higher level of abstraction. We argue that this modelling approach will provide a clearer connection between an understanding of business models and processes, and the lower-level designs typically represented in existing models.
